Predecessor of 1 lakh

To find the predecessor of 1 lakh, we need to understand the concept of predecessor and the value of 1 lakh.

Understanding Predecessor
The predecessor of a given number is the number that comes before it in a sequence. In simple terms, it is the number that is one less than the given number.

Value of 1 Lakh
1 lakh is a term used in the Indian numbering system to represent 100,000. It is equivalent to 100,000 or ten thousand times ten.

Finding the Predecessor of 1 Lakh
To find the predecessor of 1 lakh, we need to subtract 1 from it.

1 lakh - 1 = 100,000 - 1 = 99,999

Therefore, the predecessor of 1 lakh is 99,999.

Explanation
The options provided are:
a) 99,000
b) 99,999
c) 999,999
d) 100,001

To determine the correct answer, we need to compare each option with the predecessor of 1 lakh, which is 99,999.

a) 99,000: This number is less than 99,999, so it cannot be the predecessor.
b) 99,999: This number is exactly equal to 99,999, so it is the correct answer.
c) 999,999: This number is greater than 99,999, so it cannot be the predecessor.
d) 100,001: This number is greater than 99,999, so it cannot be the predecessor.

Therefore, option 'b' (99,999) is the correct answer.

Summary
The predecessor of 1 lakh is 99,999. By subtracting 1 from 1 lakh, we get the value 99,999.
